Not sure if this is already known but level 75 (found by kth11211)

I think the level 44 skip has to do with getting the first jump while the enemies are still up

I think the second jump might just be on the edge of the boxes at the end but I have no idea how you pulled off that first one except you got a midair jump and picked up to box afterward

I accidentally deleted the video and I will be resubmitting the run with the correct video link

Thx for the suggestions. I thought I had an ad blocker but it's just not working.
